Ok im going to be replacing my clutch and I would like to know what would be the best way of going about dropping the transmission.
 
You need to buy or borrow a transmission jack. Sure any jack would work to get it out, but putting it back in it where a tranny jack shines.

I have this one and love it

But it was like $299 best money I ever spent as it makes it so much easier, I wonder how I did it with a floor jack. Oh I know, countless hours:dita:

I would also support the rear of the engine as it will want to drop down way to far.

Ideally I would have an engine hoist to use, but I never know how many tools people have access too.

I have used 2x2 heavy steel bar that fits inside the fenders, you could use a 4x4 too, provided its a nice strong one.
From there I use some tie down straps to bolts on the back of the heads to carry some of the weight. Your not holding the whole engine, just the rear.

So I put a jack under the tranny and remove the cross member and lower it a bit, then support the rear of the engine and then start pulling stuff off.

Edit: if this is your first attempt, I would get some help. Tranny's are very heavy and can cause serious damage to your body parts. Having an extra set of hands will help when your using a floor jack and the transmission falls off.
 
Strategy also helps. Remove the xfer case before the xmission and the xmission will be much lighter and more balanced.
 
A bottle jack on a solid block strategically placed so that it contacts a corner of the engine block near the rear of the oil pan works well for engine support too. Or you can place a 2x4 block directly under the oil pan with the jack. I second the trans jack suggestion, but consider coming in from one side or the other with the jack as opposed to having the front wheels of the jack facing the front of the rig. This can be especially important on the install portion. It really sucks to have the front wheels of your trans jack encounter something, like your bottle jack with about a one inch gap between the trans and the back of the engine. The other key is to get the rig lifted up off the ground evenly as high as you safely can do. The problem with a trans on a trans jack is that even with it bottomed out, you still have to be able to clear the exhaust pipes and frame. Otherwise you wind up wrestling the trans off the jack to clear, which isn't that big of a deal during removal, but sucks major balls when you're trying to wrestle it back onto the jack under the rig.

Yeah thats gonna be a pain in my a$$ my driver side header goes right under the left side of my trans :mad5: and this would be a great time to have a non stock suspension and have few inches of lift but got to get I got to get it drive able before I lift it
 
I'm talking about ramps or something similar. Most people don't have the luxury of a hydraulic hoist in their home shops or driveways. You gotta have a way to give yourself adequate clearance between the frame and the ground. Now I will say that my trans dropping experience has been solely with 727 autos, which are a one-piece case. With the manual trans, I guess you can always separate the rear gear box from the bell housing and take it out in two pieces if it comes to that.
 
I use a lot of wood, as that all I had when I was a kid, so I always have some big blocks laying around. Those steel ramps work great too.
Post a picture of your Scout too.
 
Just do not use cinder blocks. Had a local guy suffer a long lonely and agonizing death after a cinder block that was holding up his car crumbled while he was under it. Someone found him still stuck under the car a couple of days later. The fd in my handle stands for fire department.

Yeah I have it sitting on cinder blocks right not I tried it before but I had the blocks sitting the sides and they just crumbled away
 
No good. 8000 lb or better ramps and/or stout jack stands under the axles on a hard, level surface would be the way to go. When bodies are slithering underneath, its tough to call any safety precaution overkill.
 
Well I haven't been on here in a while I dropped the transmission and freed up my clutch disc and put it back together got it to running and didnt hook up the shifter for the transfer case just to see if it would work and the clutch works but it the transfer case was in neutral so when I tried to drive it it didn't go anywhere so I cut it off to get under it and put the shifter back on and after that I couldn't get it to fire up when I tried to start it and since I've been working on my car since it gets me from point a to point b with very little gas used my Scout has just been sitting there waiting for my car to get finished so I can finally fix it
